PdfMasher is a tool to convert PDF files containing text into a ready-for-ebook set of HTML files. Most ebook readers support PDF files natively, but it's often a real pain to read those documents because you can't control the font size of the document and have to resort to the zooming feature instead. Another drawback of PDFs on ebook readers is that annotations are not supported. Unlike other tools that convert PDFs to ebooks, PdfMasher does not try to guess the role of each piece of text in the PDF, and instead asks the user about the role of each piece of text, and does so in an efficient manner.
